Unfortunately, delivering an AR display that fills the human field of view, let alone our peripheral vision, seems to be an intractable optics problem, not readily solved by throwing more silicon at it.

I heard the other day (from a friend in a pub, but, like me, he's been in the games industry for more years than either of us can count and therefore might be privy to insider information), that the next version of Hololens will have a much wider field of view.

Luckily I had a pinch of salt handy, but I live in hope. Presumably it's a problem that will be solved eventually though, so why not this year?
